The Ultimate Octave guitar effects pedal from Fulltone is a fat distortion/fuzz with a very active tone control and a separate switch that kicks in the most searing octave-up available. In addition to volume, tone, and fuzz controls, the Ultimate Octave effect also has a Fat/Bright switch that completely changes both the distortion and octave sounds from strong, thick mids (Fat) to completely scooped out with no mids and lots of bass and high end (Bright).

I am a real big electro-harmonix fan and i have played on most of their pedals. I was searching for a unique fuzz tone that i could stand out with. After searching through a few other brands I wanted to puke. Just about when i was assuming that i would just have to break down, and stick with my trusty big muuff as my source of fuzz, I found the ultimate octave. Let me tell you this thing is insane. I play primarilly grunge and hard rock and this fits in nicely with my othr gear. I run a 20+ year old Gretsch Country Club full hollow(with earni ball rock-n-roll 10's strings) through a vox wah, mxr carbon copy delay, boss delay(the only digital pedal i own besides my tuner), big muuff pi, trex tonebug reverb(which i leave on constanly and very mildly set), mxr full bore metal(which i set the eq on crazy to get more a high gain fuzz tone with very little high frequency), ibanez tube screamer, and a boss chromatic tuner. I run this through a vox ac head and cab and it sounds incredible. I also run all this using only monster gold connector rock cables. im finally getting close to the tone i hear in my head. The next pedals on my list to purchase are the electro-harmonix small clone, the mxr script phase 90, a joe meek floor compressor, and an ISP decimator noise reducer. The next amp im getting will be the egnator tweaker 40 which is crazy awesome, and a Bugera 1960(so i can switch between a low gain amp and a high gain amp but still have that vintage luster).I would reccomend this fuzz pedal to anyone wanting a great vintage, sexy, unique sounding fuzz. It works great and is built like a tank. This many pros cant be wrong.....billy gibbons (Z Z top), jack white (white stripes), josh Homme (queens of the stone age), billy corgan (smashing pumpkins), etc. etc.

This pedal is easily the best in my arsenal of 7 pedals. It has the sexiest fuzz that i've ever heard, retaining clarity with every combination of notes , almost synth-like in precision. This pedal also doubles as an octaver, allowing for an "octave-up" from what you are playing, layered on top of the initial tone. *pros*- This pedal can sustain your tone like the dickens.- Your tone can have fuzz caked onto it beyond your wildest dreams, all at your discretion and control*cons*- Can affect the guitar tone even when not in use, but this is subtle to the point where it's almost unnoticeable.This pedal will give you many luxurious liberties.

If you want a vintage sound for your guitar this is it,it has the best of both worlds,Octave-fuzz. You can use it together or separate, if you like "The Band of Gypsys", "Jimi Hendrix" or Joe Satriani this will be the answer. when i use this pedal it transports me to the Psycodelic era. for more effectiveness use your neck pick-ups.I love this pedal since I got it the first day.

Construction wise, this pedal is built like a tank. The fuzz/gritty overdrive section of the pedal is a very tiny bit lack luster, hence the 4.5, but once the octave-up section is engaged it completely makes up for it. The octavio can be heard anywhere on the neck, works best on a neck pickup.The bright and fat switch is superb, and very thoughtful. Overall, if you are looking for a nice analog octavio pedal, you should select and purchase the Ultimate Octave by Fulltone.

This is a great octavio-type pedal, but Its a little too expensive for what it does. This pedal has a great fuzz tone, and then (to make things a little more chaotic) a another button to dial in an octave up! this pedal is sooo cool, and the octave up adds so much to the fuzz, and its great that it has two switches so you can isolate the fuzz. But this pedal cannot go totally clean.
